Question: 1 / 20

One of the roles of aspirin (ASA) in cardiac events is to:

Increase heart rate for better circulation

Help stop clotting in the arteries

Aspirin (ASA) plays a crucial role in the management of cardiac events due to its properties as an antiplatelet agent. By inhibiting the aggregation of platelets, aspirin helps prevent the formation of blood clots within the arteries. This is particularly important during a cardiac event, such as a heart attack, where a clot can block blood flow to the heart muscle. By reducing the ability of platelets to clump together, aspirin aids in maintaining blood flow, which can mitigate damage to the heart.

The other options do not accurately describe the primary function of aspirin in this context. Increasing heart rate does not directly relate to aspirin's function, nor does aspirin significantly decrease blood pressure or enhance oxygen uptake by the heart. Instead, its main contribution lies in its effect on preventing clot formation, allowing for better blood flow during critical situations.
